Working with the LSV2 – Helpful Video Tutorials

Jake filming the LSV2 Tutorials

As interest in the Leeds Spectral Vision System (LSV2) continues to grow, we are excited to introduce a library of user friendly video tutorials showing how to screen, view, and document evidence in the forensic lab.  Visit Leeds’ YouTube LSV2 Tutorials playlist and make sure to subscribe to our YouTube channel as we will continue to add new videos over the coming weeks and months.

We’ve started by addressing a few common inquiries from the field:  1) how to adjust the arm tension to screen at various fields of view, and 2) how to adjust the LSV2’s head for tip, tilt, and rotation (or pitch, roll, and yaw).

LSV2 ARM ADJUSTMENT

Knowing how to adjust the LSV2 arm tension will allow for easier workflow when screening evidence at close-up and overhead ranges, as well as every distance in-between.  If the arm’s vertical tension adjustment is set correctly for the height range an examiner is working in, screening is very seamless.  However, if the arm tension adjustment is off, this can cause the LSV2 head to move when screening evidence.  Watch Leeds LSV2 Arm Adjustment Tutorial to learn how to make simple adjustments to the arm tension to hold the LSV2 head in place at different heights.

LSV2 HEAD ADJUSTMENT

Controlling the LSV2 head’s tip, tilt, and rotation, allows for the examiner to screen evidence in a variety of positions versus having to adjust the evidence itself.  Adjusting the LSV2 head is easily explained in this Leeds LSV2 Head Adjustment Tutorial showing the 3 different levels and locking mechanisms to control pitch, roll, and yaw.

DIOPTER SELECTION & DIFFERENTIATION

The LSV2 offers 3 different diopter options:  +1, +2, and +3.5.  In addition, the LSV2 offers the option of selection no diopter.  Determining which diopter to use at which working distance can, in some circumstances, be a bit tricky.  Watch our LSV2 diopter tutorials to learn about diopters and understand the best general practices for using diopters when viewing, screening and documentation of forensic evidence.
